Fixes #1155

Merge upstream changes

Port c07cca4727 to glitch-soc

* Disable incorrect check for hidden services in Socket

Hidden services can only be accessed with an HTTP proxy, in which
case the host seen by the Socket class will be the proxy, not the
target host.

Hidden services are already filtered in `Request#initialize`.

* Use our Socket class to connect to HTTP proxies

Avoid the timeout logic being bypassed

* Add support for IP addresses in Request::Socket

* Refactor a bit, no need to keep the DNS resolver around

Unlike upstream, kept the direct timeline endpoint, as it is still of use in
glitch-soc.

Avoids jumping the scroll around vertically when giving it focus and
editing long toots.

Fixes #1153

Port 99924f282f to glitch-soc

Port dc88d226e1 to glitch-soc

The instrumentation code was used for StatsD metrics collection
prior to the switch to the nsa gem and should have been removed
at that point as it no longer does anything at all

Use the smallest preset expires_in such that the new poll would
not expire before the old one.

In the typical case of a quick delete & redraft, this results in
using the same poll duration.

Fixes #10567

* Add request pool to improve delivery performance

Fix #7909

* Ensure connection is closed when exception interrupts execution

* Remove Timeout#timeout from socket connection

* Fix infinite retrial loop on HTTP::ConnectionError

* Close sockets on failure, reduce idle time to 90 seconds

* Add MAX_REQUEST_POOL_SIZE option to limit concurrent connections to the same server

* Use a shared pool size, 512 by default, to stay below open file limit

* Add some tests

* Add more tests

* Reduce MAX_IDLE_TIME from 90 to 30 seconds, reap every 30 seconds

* Use a shared pool that returns preferred connection but re-purposes other ones when needed

* Fix wrong connection being returned on subsequent calls within the same thread

* Reduce mutex calls on flushes from 2 to 1 and add test for reaping

This fixes multiple issues, while adding few computations

This *does* break things, as `shouldComponentUpdate` assume the
children to never change!

When editing a custom filter, select the shortest preset duration that
still covers the remaining time of that filter.

Fixes #9506

Resolve #11187

Partial port of ccc7fe3e1d to glitch-soc

It doesn't ensure the field isn't changed, just that it isn't submitted if
the field isn't visible. Ensuring the field isn't changed would require
reworking the “always show CW field” feature.
